I'm having some more spare time now and I'll spend most of it in the darkroom. So I have quite a few questions I've been asking myself for a while. I'm sort of tired of grain. I've been looking for ISO 50 films, but the only way to get some seems to be ordering from the UK. However, I thought about maybe pull-processing my Ilford FP4 rolls, which is rated ISO 125. I've been mostly pushing film and the only time I actually pulled, it was iso800 accidentally shot at 400 settings. So I don't know how the FP4 might respond. My concrete question is: if I pull the fp4 to approximately iso 50, will the grain be tighter or is it just a waste of time and film? Since it's already pretty slow film, will it get awfully darker? Also, I assume a fine grain developer would be preferable. But is it imperative to rather good results? The shop I buy chems from only has Ilfosol S.
